Edwal Hypo Check tests your fix solution for exhaustion due to silver saturation.
In the Box
- One or two drops will test the fixer and, if the fixers still OK, no harm has been done to the bath.
- If the addition of Hypo-Chek produces a cloudy precipitate, the bath is exhausted and the fixer should be discarded.
